5.2 Calibration
After the maintenance of the electrochemical gas sensor, a full calibration of the system is
required.
To ensure an accurate calibration, each sensor needs stabilizing for a certain period of time.
Ideally calibration should be carried out with a standard gas or with one of the gases which
can be generated by using a Bionics Instrument calibration kit (see appendix 2).
It is recommended to use a gas concentration which is equal or nearly equal to the specified
full range of the gas sensor.
5.2.1 Setting-up the calibration procedure
- Fill the “Tedlar” bag with calibration gas of the required concentration level
(Please refer to the instructions with the calibration kit for preparation of calibration gas).
- Assemble the “Tedlar” bag, flow-indicator, flow cap and calibration pump as shown in fig.
5.2.1 (use PTFE tubing to connect the items).
- Insert the gas sensor into the TX-KFP unit.
Fig. 5.2.1
- If an alarm/control unit is
connected to the system, ensure
that this unit is set to “stand-by”
mode.
- Disconnect the power/signal
cable from the TX-KFP unit.
- Connect the calibration signal
cable CC-1 to the unit and the
disconnected power/signal
cable.
- Connect the test leads either to
the multi-meter or to the local
indicator.
